Friday Fun: Five Gross and Goofy Body Facts

  1. A tiny, monkeylike creature called the tarsier has the largest eyes compared to its body size. But the biggest eyes of all belong to the giant squid. Its volleyball-sized eyes are a hundred times larger than yours!

  2. A praying mantis has super-sharp eyes. The hungry hunter uses them to spot the slightest movements up to 60 feet (18 meters) away.

  3. The eyes of hawks and eagles see eight times more clearly than the sharpest human eyes. They have two foveae and five times more cones. A golden eagle can see a rabbit from 1 mile (1.6 kilometers) away. Just imagine having eyesight like that!

  4. Tyrannosaurus rex may have had the best eyesight ever. Some scientists say the fearsome dinosaur may have been able to see thirteen times more clearly than a person.

  5. Giant clams can have thousands of eyes, but they’re very simple. They can sense light and motion, but they can’t form images.
